Ap li ati n filed February 1, 1906. Serial in. ass-.996.

To all whom it may concern.- Be it known that I, JULIUS O. HERRMANN,

a citizen'of the United States, residing at St. Louis, Missouri, have in vented a certain new and useful Im rovement in Car-Roof Doors,of l wing is a full, clear, and exact description, such as will enable others skilled inthe art to which it appertains to make and use the same, reference being had to the ac-f companying drawings, forming part of this specification, in which- F'gure 1 is a plan view of a car-roof'provided with a door embodying the features of my invention. Fig. 2 isa transverse sectional view of the parts shown in Fig. 1. Fig. 3 is av longitudinal sectional view through approximately the center of the roof and door. Fig.

. 4 is a side view of the roof and door; Fig. 5

is a detail view showin the locking means at one end of the door 'w 'ch prevents it from being raised; and Fig. 6 isa-view similar to Fig. 4,, showing a modified form of my invention.

This invention relates to freight-cars; and

the object of the invention is to'provide a freight-car having a large opening in its roof,

which closed by a door of novel construe" I ,tion.

One essential feature of a freight-ear is that it shall have a rooi which is absolutely watertight, and great trouble has been" experienced '5 in trying to produce a water-ti ht car-roof having an. opening closed by a 001". With this object in view Ihave devised a roof-door which is so constructed that it is impossible for rain or snow to enter the car through the opening in the roof which the door closes.

Another object of my invention is to rovide a car having an opening in. its roo extending approximately the full width of the car, which opening is closed by a door that is so constructed that the rigidity of the car is not lessened any by said opening. Referring to the-drawings, which represent the preferred form of my invention,- 1 designates the sides of a car provided with a roof 2, preferably formed of corrugated sheet metal andhavinglano enin '3, whichextends approximately t e in widt of the roof, said opening being longer than it is wide. Extendrecarlines 4, which are mortised e'usual rid,5.3;e=1 o 5 and purlins- 'ing which the door closes.

6, and 'connected to each of'said carlines by bolts is a cross-ridge 7 of a proximately the formshown in Fig. 2, sai ridge extending above the surface of the corrugated roof, which is connected thereto, as shown in Fig. 3, so as to form a water-tight joint. Preferably each curline is protected by an angle 8, connected to its lower edge and extending a portion of its length.

The'door which closes the o p ening above referred to normally rests on said cross-ridges and runs on tracks 9, which are connected to the roof, and said door is preferably made up of sheet-metal plates 10, riveted together,

saiddoor being strengthened by longitudinally-extending angles 11 and transverselyextending an les 12, secured, respectivel ,to

the under si e and to the upper side 0 the.

door. It should be understood, however, thatthe door need not necessarily be formed corrugated metal could, be used and other commercial-shapes could bejused as the strengthening means without departing from the scope of my invention;

of plates and strengthened by angles, as

The'tracks 9 are formed-of angles, which are so disposedwith relation to the longitudinal angles 11 at the sides of the door that it is impossible forrain or snow to enter the openvided at each side with two sets of rollers 13 and 1 5, which travel on said tracks, "the rollers 13 traveling onthe horizontal Web of the track and the rollers 15 traveling on the vertical web of the track, as shown in Fig. 2. By mounting therollers in this manner a very rigid construction is insured, and the door is held securely in position. .As shown in Fig. 4, the u per edge of the vertical portions of the trac s is provided with inclines, so that when the door is opened the rollers riding up said inclines will raise the door ofi the cross-- ridges, and thus provide a clearance for the heads of the rivets which securethe plates of the door together and also the rivets which secure the transversely-extending an le at the rear end of the door. The cross-rid the left-hand side of the door-opening is provided with 0 enings or notches 16to provide.

to the underneath side of the .door. to cover The door is proge ataclearance. or the-intermediate angles 11, A and the rollers 15 and plates 24 are fastened in dotted lines in Figs. 1

as having a perforated device 21, which proj ects through an o ening in a hasp. 22, fastened to 'the underneat side of the door, as shown and 3.

To prevent the rearward end of. the door from being raised, the cross-ridge 7 at the right-hand side of the door-opening is provided with a plurality of plates 26, each having a slot that receives the vertical leg of a longitudinally-extending angle 11, the horizontal leg of the angle being removed, as shown in Fig. 5, to permit-the vertical leg to enter the slot in said plate. The plate 26 also acts as a buffer or wear plate to be engaged by the horizontal leg of the angle 11. when the door is moved into position to close the opening. If desired, the opening can'be closed by a pair of doors, which in construction are practically the same as thesingle do'or', this form being shown in Fig. 6.

From the foregoing description it will be seen that -I have provided a door which is very strong, but not cumbersome, so that it can be easily operated, and, moreover, is so constructed that the roof of'the car is perfectly water-tight.

' Having thus described my invention, what- 'Iclaim as new, and desire to secure by Letters Patent, is

1. A box-car provided with a rooi having an opening therein, a closure for said opening, said closure extending beyond all sides of said opening when in operative position, guides carried by the roof for said closure to I travel on, and vertical rollers interposed between said closure and said guides;'substantialiy as described.

2. A box-car provided with a roof having an o ening therein, a closure for said opening, ongitudinally-extending guidesfor said closure, rollers interposed between said closure and said guides, and inclined surfaces on said guides adjacent to the rollers when the closure is in operative position whereby said closure will be raised .to provide for a clearance of underlying parts when it is moved into inoperative position; substantially as described.

3. A car having a roof provided with an opening, a closure for said opening, rollers for scribed.

5. A car provided with an approximately peaked roof having an opening therein, ridges projecting above said roof around said opening, a door covering said opening and pro ect- .ing beyond said ridges, rollers for supporting said door, a projecting member at one end of said door for engaging a cooperating sta ti onary member, and a cooperating hasp and eye at the opposite end of the door to enable it to be locked in position; substantially as described.

6. A car having a roof provided with an opening, carlines extending from side to side i of the car at the ends of said opening, cross ridges connected to said carlines and projecting above the surface of the roof, tracks at the sides of said opening, a door closing said opening and normally resting on said crossridges, and rollers carried by said door; substantially as described.

7. A car provided with a roof having an opening therein, cross-ridges located at the. ends of said opening and pro ectmg above the roof, a door closing said opening and. provided with strengthenmgdevices on its run derneath s1de, open1ngs in one of sald crossproper alinement; substantial ly,

ridges to provide a clearance for said strengthening devices, and means connected to the door for closing the openings in the crossridge when the door is closed; substantially as described.

In testimony whereof I hereunto ailix my signature, in the presence of two witnesses, this 26th day of January, 1906.
